Specify what should happen when an element's content is too big to fit
in a specified area. (An alternative to IFrames.)

Tired of IFrames? The CSS overflow property, which specifies what should
happen when an element's content is too big to fit in a specified area,
can be used as an alternative.

The Downside

This property doesn't provide the advantage of quick updates that IFrames
do because the frames' content isn't kept in an external file. Therefore,
this method is only suggested to be used for content on one page.

Start off by placing the following code in the head section of you page.(between
<head> and </head>)
